The Predictors of Postoperative Cerebrospinal Fluid Leak in Endoscopic Endonasal Pituitary Surgery: The Role of Tumor Volume.

 Postoperative cerebrospinal fluid (Po-CSF) leak is still a challenging complication of endoscopic endonasal skull base surgery. However, data describing the predictive factors of Po-CSF leak in pure pituitary adenomas is lacking. Aim of this study is to determine the risk factors of Po-CSF leak in a pituitary adenoma group operated via pure transsellar endoscopic approach.

Predictive value of ALDH1 and CD44 positivity for radiotherapy response and prognosis in early-stage glottic laryngeal squamous cell carcinoma.

To evaluate the predictive value of CD44 and aldehyde dehydrogenase 1 (ALDH1) expression for prognosis and radiotherapy (RT) response in patients with early-stage laryngeal cancer receiving RT. Forty-four patients with early-stage laryngeal cancer diagnosed between 2002 and 2016 were included in the study. The correlation between RT response and pre-treatment immunohistochemical ALDH1 and CD44 staining was evaluated.

Alternating pattern of rhino-orbital-cerebral mucormycosis with COVID-19 in diabetic patients.

Purpose: Our aim was to analyze the patients with diabetic rhino-orbital-cerebral mucormycosis that we have treated in our clinic in the last 5 years, and to reveal the altering conditions with COVID-19.

Materials And Methods: A retrospective study was conducted on 39 rhino-orbital-cerebral mucormycosis (ROCM) patients with diabetes mellitus between 2017 and 2022. The patients were divided into two groups as those associated with and not associated with COVID-19 and compared.

The Results of Cochlear Implantation in the Inner Ear Malformations.

Background: Cochlear implants are arguably the most successful neural prosthesis today. Cochlear implantation has several difficulties in patients with internal ear anomalies. This study was performed to analyze intraoperative, postoperative findings, and auditory performance of 55 patients who had inner ear malformations and were treated with cochlear implants at Otorhinolaryngology Department of Çukurova University Hospital.

Endonasal endoscopic approach for sellar metastatic pathologies: a national observation.

Purpose: Sellar metastases are rare lesions. Recent improvements in diagnosis and treatment strategies have prolonged survival but increased the probability of metastatic tumors. Evaluation with clinical symptomatology and meticulous laboratory examination is crucial.
